DEFINITION OF STARTUP PHASE OPTIMIZATION OF STARTUP OPERATIONS IN LARGE CONSTRUCTION PROJECTS (INTERNATIONAL AIRPORTS- KSA) BY OMRAN ZAIN OMRAN
· To carry out an in depth examination of the startup phase of construction projects, specifically airports. · To study and analyze the role of the startup phase of projects in relation to project cost, time, and efficiency. · To examine the startup procedures. To come up with a comprehensive program or guidelines · that will help people involved in the construction industry. OBJECTIVES OF THE STUDY OPTIMIZATION OF STARTUP OPERATIONS IN LARGE CONSTRUCTION PROJECTS (INTERNATIONAL AIRPORTS- KSA) BY OMRAN ZAIN OMRAN
GENERAL TYPES OF STARTUP PHASED STARTUP TURNKEY STARTUP 2 1 The contractor would undertake the design and commission a complete installation until the time when the client would “turn the key” for full operation. Large systems are handed over to the client systematically throughout the commissioning period. Individual units are tested and rendered operational. • The choice of either type is dependent on number of factors on which a decision is made. • Client’s resources • Size of the project • Complexity of the project • Time constraints OPTIMIZATION OF STARTUP OPERATIONS IN LARGE CONSTRUCTION PROJECTS (INTERNATIONAL AIRPORTS- KSA) BY OMRAN ZAIN OMRAN

CONCLUSION It was strongly evident that there is a tangible shortage or lack of information and research on airport projects startup phase locally. This statement was found to be equally true on local and foreign airports. 1. Despite some similarities, in concept, in structuring the startup organizations, no specific and common guidelines on which airports’ startup procedures were based on in these airports. 2. Transition plans were given a significant weight, importance, and handled as an integral part of the startup plan In the case of the studied foreign airports. In the case of the studied local airports it was treated with significantly less importance. 3. Munich International airport hired a German specialized consultant to handle the transition stage. The consultant started to prepare the Munich move more than 1½ years prior to the opening. Beside the transition consultant, 14 different work groups were defined. These work groups had the objective to assure important premises for a smooth transition. 4.

CONCLUSION In the case of local international airports, some regulations were found to dominate the obstacles when planning for startup phase, especially when they are not taken into consideration. Such regulations or obstacles were: 5. Implementation of the lowest bidder concept on the procurement process of materials and parts during startup phase. Denial of the provision of Bulk Visas for the hiring of required foreign personnel for the completion of the startup phase. Denial of the importance in treating startup requirements as a special case which needs to be expedited due to the nature of the startup phase. Denial of the provision and hiring of specialized consultants in temporary bases for required specific tasks during startup phase.

CONCLUSION If no action is taken in response to the increased task uncertainty of a startup, additional resources must be provided. The cost of extending the time allotted for the startup may be the easiest cost to bear. But, it would be less costly to add people and to spend money in ways that would reduce the startup time. Some of the ways in which this is done are to: 6. Add human resources: Additional technical personnel are made available, and extra maintenance people may be kept on as well. Add material resources: Extra spare parts may be kept on hand, along with complete units of critical pieces of equipment. Add money: Budgetary restrictions and controls may be relaxed: procurement procedures may be streamlined and simplified so that operating and technical personnel may quickly order and obtain critically needed materials. If all else fails, the startup will simply take longer to complete, schedules will not be met. Time is the resource of last resort, and the one that requires the least planning and creativity to make available.

CONCLUSION 7. In the case of local international airports, the utilization of experienced personnel within the organization, from other in-Kingdom airports, is not a common practice. Delays, postponement and slippage in the startup schedules result in shortening the lifetime or even voiding the contractor warrantees provided as part of their contractual requirements and deliverables. 8.

RECOMENDATIONS 1. Explore in depth and further study the startup phase procedures and operations of other public projects in the Kingdom of Saudi Arabia. Documentation for startup phase guidelines and procedures to be formatted and saved in proper format i.e. hard copies, electronic copies, etc. and make them accessible to planners and professionals for reference. 2. Develop training courses and workshop sessions on startup phase planning, practices, challenges, etc. for planners and professionals in order to enhance perception and decision making capabilities in this field. 3. 4. Allocate funds to local universities to adapt researches and studies on startup operations and practices in the Kingdom of Saudi Arabia. Develop checklists on startup phase planning and procedures for the use of the government and private sectors projects in the Kingdom of Saudi Arabia. 5.
